Why Do Different Bottles Of Human Serum Sometimes Look Different From One Another?
Innovative Research Products go to great lengths to ensure that our human sera are the most consistent products commercially available. Although our human serum is manufactured using raw material from congruous donor pools and according to time-tested protocols, it is ... Continue reading →
Why Are Some Of Your Antibodes Supplied With BSA And Azide?
Bovine Serum Albumin (BSA) is a protein-stabilizing agent and Sodium Azide is a preservative that prevents bacterial growth. The carrier protein and preservative are added to increase functionality and longevity of the antibodies. Antibodies supplied with BSA and Azide can ... Continue reading →
How Is Streptavidin Used?
Streptavidin has a high affinity for biotin, with Kd = 1 x 10E-15 moles/L (Green, N.M.  Adv. Protein Chem. 291:85). Streptavidin covalently conjugated to a reporter such as a fluorochrome (R-PE or FITC) or an enzyme (HRP or alkaline ... Continue reading →
What Species Produce Monoclonal Antibodies?
Monoclonal antibodies are produced in mice, rats, hamsters, and rabbits. First, the host animal is injected with an antigen to initiate a humoral immune response. In most procedures, spleen cells from these hosts are fused in vitro with cultured malignant ... Continue reading →
What Species Produce Polyclonal Antibodies?
Polyclonal antibodies are mixtures of related antibodies that are derived from blood serum, harvested from previously immunized animals. Serum-derived polyclonal antibodies can be produced in virtually any mammal. However, most polyclonal antibodies are produced in animals with large blood volumes ... Continue reading →
How Is Dialyzed FBS Processed?
It is dialyzed by tangential flow filtration against 0.15 M NaCl using a 10,000 molecular weight cut-off membrane until the glucose level is less than 5 mg/dL. Since this is not exhaustive dialysis, low molecular weight dialyzable components, such as ... Continue reading →
How Do I Heat Inactive Serum?
Heat at 56°C in a water bath for 30 minutes. Swirl bottle every 10 minutes or so. For accuracy, use a second bottle of similar size and add the equivalent volume of water to this bottle. Place a thermometer in ... Continue reading →
Why Would I Heat Inactive Serum?
Heating inactivates complement. Active complement can participate in cytolytic events, contract smooth muscle, release histamine from mast cells and platelets, and activate lymphocytic and macrophage cells. Applications where heat inactivated serum is recommended include immunological studies and culturing ES cells, ... Continue reading →
Why Does Material Precipitate In FBS Upon Storage In The Refrigerator?
FBS is not pre-aged. When stored at 2 to 8°C, the possibility exists for various proteins and lipoproteins in serum (e.g., cold agglutinins, fibrinogen, vitronectin, etc.) to aggregate, and form either perceptible material or observed turbidity. This should not affect ... Continue reading →
Do You Have An ELISA Kit For The Detection Of Serum Amyloid A (SAA) In The Rat?

What Is An ELISA?
Enzyme-linked immunosorbent assay (ELISA) is a test that uses antibodies and color change to identify a substance.
ELISA is a popular format of a "wet-lab" type analytic biochemistry assay that uses a solid-phase enzyme immunoassay (EIA) to detect the presence of a substance, usually an antigen, in ... Continue reading →

- A buffered solution of the antigen to be tested for is added to each well of a microtiter plate, where it is given time to adhere to the plastic through ... Continue reading →
Why Do I Notice Particulate Matter In Some Human Serum?
Due to a diet higher in fats and oils, human serum typically contains higher levels of lipids than serum from other sources. Even after sterile filtration through 0.1mm filters, particles remain suspended in solution that can aggregate and precipitate as a result of subsequent freezing, thawing and/or heat-inactivation. It is for this reason that we suggest minimizing such temperature changes. The presence of particulate matter does not indicate contamination of any sort, and does not negatively impact the serum's performance.Continue reading →
How Long Can Frozen Human Serum Be Stored?
Although it is impossible to claim stability data for every possible application and use for human serum, we conservatively estimate that if this product is stored properly at -20C, it can be used for 5 years from the date of manufacture without any decrease in product performance. Storage at any other temperature may affect results.Continue reading →
